The three given lengths on the right sides of the diagram add to 9
Since we're told the garden is a SQUARE, we know that the 3 lengths on the bottom of the diagram must add to 9.
In other words: x + (missing middle length) + 3 = 9
Solve to get: middle length must be 6-x.
At this point, we can find the areas of all 9 rectangles by applying the formula area of rectangle = (base)(height)
The sum of the areas of the regions planted with peas is equal to the sum of the areas of the regions planted with tomatoes.
We can write: 3x + 3x + 3(6-x) + 9 + 9 = 3x + 3(6-x) + 3(6-x) + 9
Expand: 3x + 3x + 18 - 3x + 9 + 9 = 3x + 18 - 3x + 18 - 3x + 9
Simplify: 3x + 36 = -3x + 45
Add 3x to both sides: 6x + 36 = 45
Subtract 36 from both sides: 6x = 9
Solve: x = 9/6 = 3/2 = 1.5
Answer: C
